QML gives more freedom with regards to what the user interface can look like -> more engaging and natural interfaces

Phonon allows for rapid creation of media applications -> more time for actual features

In conclusion: Phonon and QML together will bring us better designed, better looking and feature rich media applications such as video players. Of course it also allows non-media centered applications to easily emit audio or video.

Finally, if you are a developer you might want to look at this code sample, which might very well be how one will use Phonon in QML.

QtMultimediaKit is not part of Qt, so it is an own QML module, meaning you’d have to import both QtMMK and Phonon in the same file to get to any such name conflict. Now I’d think that if you import two multimedia abstraction modules, you are probably doing something wrong ^^

It is not a videowidget, internally it currently uses the experimental VideoDataOutput, but that is about to change. I’ll blog some more technical detail in the next couple of days though, so just stay tuned ^^
